III - Pressure

track pressure / Use of tyre warmers

The pressure should be set at ambient temperature and depends on the tyres you have chosen to mount on your motorcycle:

For riders competing with the MICHELIN Power Performance range, Michelin’s technical teams can provide expert advice on

adjusting tyre pressure depending on:

•Air/track temperature

•Track abrasiveness

•The rider’s level of skill

Correct pressure enables optimum performance levels to be achieved

(1) Pressure taken with tyre and rim at ambient temperature, just before the f irst ride or just before f itting the tyre warmers.

(2) After riding on the track and before street riding, you will need to adjust the cold tyre pressure to the manufacturers’ recommended setting.

Use of tyre warmers

MICHELIN Power Slick MICHELIN Power Cup and MICHELIN Power Cup Evo are designed to have a short warmup time use of tyre

warmers is not mandatory

When using tyre warmers the pressure set at ambient temperature before the f irst ride should be the same as without tyre warmers

Using tyre warmers makes it possible to reach operating pressure more rapidly In no cases does the use of tyre warmers make itpossible

to start with a lower pressure The main aim of using tyre warmers is to reach the optimum operating pressure faster to save on warmup

time at the beginning of the ride

Tyre warmers should be used with a temperature of 90C for at least 1 hour before the f irst ride

In cold conditions tyre warmers should not be set to too high a temperature The colder it is the lower the temperature of the tyre warmer

should be in order to avoid the situation of tyres cooling down while riding Tyres that cool down while riding can skew the riders perception

of actual performance levels

Use of tyre warmers with the MICHELIN Power Rain is not mandatory If it is used they should be adjusted to temperature of 40C

These pressure recommendations are given for track use For road use the manufacturers tyre pressure recommendation applies With

track tyres approved for the road or road tyres for occasional track use it is essential to ensure that tyre pressure is returned to the correct

level for road use following use on the track
